Rockwell Automation announces the release of a new universal visible-blade disconnect switch featuring global ratings UL, CSA, CE and CCC to reduce design complexity for panel builders around the world.
The new Allen-Bradley Bulletin 1494U visible-blade disconnect switch provides capabilities for applications with 30, 60 and 100 amps. Rockwell Automation will extend the Bulletin 1494U line next year with ratings up to 600 amps.
According to Steve Amor, product manager – industrial components, Rockwell Automation, panel builders are working with customers from various parts of the world, and are required to meet a number of international standards. The new Allen-Bradley Bulletin 1494U visible-blade disconnect switches are designed and tested for global acceptance and use.
Key features and advantages of Bulletin 1494U visible-blade disconnect switches include visible confirmation indicating ON/OFF positions while isolating motors, motor controllers and other loads from a supply circuit; universal application reducing inventory; and choice of a number of styles and options to meet specific application needs, including nonfusible or fusible versions, with fusible version having short-circuit protection.
The new disconnect switch can also be connected for rod or cable operation; cable option allows users the flexibility to mount the switch anywhere in the panel, regardless of the handle’s location.
The optional back-of-hand protective cover for the line and load sides, and auxiliary contacts for status notification to the control system provide enhanced safety for customers. The disconnect switches are also NFPA 70-compliant with the switch, operating mechanism and handle connected at all times, regardless of whether the panel door is open or closed.
The compact design of the new Bulletin 1494U disconnect switch saves users panel space with a 30 percent smaller footprint than previous offerings. The switch, mechanism and multitap lugs together have an industry-leading footprint that is almost 50 percent smaller than previous combinations.
Provided standard on the universal disconnect switches, aluminium lugs accept copper and aluminium wiring for easier installation. Fuse clips are pre-installed for the fusible version. The multiport lug connector enables wires to be connected directly to the disconnect switch, eliminating the need for users to wire through a distribution block.
